To all whom it may concern:

Be it known that I, Fnnnnmcx G. WAcKnn, a citizen of the United'Statesresiding at Chicago, Cook county, Illinois, have mvented certain new anduseful Improvements in Metallic Receptacles, of which the followin is aspecification.

y invention relates to metallic receptacles such as barrels, casks,drumsand the like, and the object thereof is to improve the constructionparticularly as to the body of the barrel and the so-called rollinghoops thereof, thereby producing an improved and stronger construction.

In the drawings Figure 1 is an elevation tion; Fig. 2 a sectional detaiof aportionof the body and a rolling hoop showing the 1nitial stage ofthe formation of the structure; Fig. 3 a similar view but illustratingthe =final structure, and Fig. 4 a detail slmllar to Fig. 3 butillustrating a modified form of construction particularly as respectsthe rolling hoop.

Referring to the embodiment of my invention as herein shown, the barrelor drum includesthe cylindrical body portion 1 and rolling hoops 2,which as shown are generally two in number, located as shown in Fig. 1.As shown in Fig. 2 the hoop consists of a substantially centralcircumferential bead portion 2 and the two flange portions 2". Inpractice each hoop is of slightly larger diameter than the externaldiameter of the body of the barrel, thereby fitting loosely thereupon.

In the production of my improved metallic receptacle each hoop isslipped over its end of the barrel and the following rolling operationsare performed in order to produce the final structure illustrated byFig. 3.

After the hoop is in proper position with relation to the body of thebarrel such body is rolled outwardly at two points to form the outwardlyextending beads 1" at the outer edges of the flanges 2". At the sametime or as the result of a subsequent rolling opera tion the body of thebarrel, located between these beads 1, is rolled outwardly as shown inFig. 3, thereby forming a seat for the hoop, which seat is tightlyforced against the hoop flanges, and the central part of such expandedportion of the barrel, as illustrated at 1, is expanded outwardly andinto the bead portion 2 of the hoop. In the formation of the beads 1 andthe expanding of stretched, thereby exerting a tension against the inneredges or corners of the bead 2, with the result that the associatedparts are kept in close and tight relationship, including the flanges 2"in contact under pressure with the beads 1. The joint displacement ofregistering zones of both the barrel-body and the hoop (namely the zoneswithin the width of flanges 2") outwardly, each beyond its initialcircumferential position, as shown in Fig. 3, insures firm and evenseating of the hoop on the body. Moreover, expanding of the barrel bodymakes a truss or locally bulged construction which is very practical andefiicient as the weight of the barrel in rolling is borne by theserolling hoops and any tendency of flattening ofthe truss is effectuallyresisted by the construction thus provided. The beads 1 and the outwardexpanslon of such central part therebetween are preferable but notessential" in the broader aspect of my invention.

In Fig. 4, I have illustrated a modified form of constructionparticularly with respect to the rolling hoop 3 which is here shown asof I-beam construction. In this form of metallic receptacle the sameheads 1 are formed in the barrel body and such body is outwardlyexpanded at 1 to bear tightly against the base of the I-beam, it beingunderstood that such hoop fits the barrel body loosely just as the hoop2 already described;

I claim:

1. A metallic barrel including a body having two small parallelcircumferential outwardly directed beads, and a large outwardly directedbead located intermediate the small beads, and a rolling hoop having acentral portion interlocking with said large bead, said hoop havinglaterally directed flanges bearing against said small heads.

2. A metallic barrel including a body, and a rolling hoop having anoutwardly directed head, the body of the barrel having a circumferentialbead extending partially into said hoop bead and bearing against theinner corners of the hoop bead with pressure.

3. A metallic barrel including a body having two parallelcircumferential beads and an intermediate circumferential bead, and arolling hoop having intermediate its width a circumferential beadcooperating with the intermediate bead of the body, the edges of thehoop bearing against said two parallel circumferential beads of the bodyaccording to the pressure exerted by the intermediate body bead upon itscooperating bead.

4. A metallic barrelincluding a body having two parallelcircumferentialbeads and an intermediate circumferential bead, and a rolling hoophaving intermediate its width a circumferential bead coiiperating withthe intermediate bead of the body, the edges of the hoop bearing againstsaidtwo parallel circumferential beads of the body according to thepressure exerted by the intermediate body bead upon its cooperatingbead, the body of the barrel lying between such two parallel beads beingdisplaced outwardly against and into'the bead of the hoo and out of linewith the main body of the barrel.

5. A metallic barrel including a body having circumferential parallelbeads and an intermediate portion integrally connecting said heads, arolling hoop around said intermediate portion, said intermediate por-'.

tion of the barrel body being displaced outwardly from the plane of theremainder of the body and bearing against the hoop.

6. A metallic barrel including a body and a rolling-hoop therearound,the body having beads snugly paralleling the hoop-edges, and a zoneintermediate the beads outwardly displaced beyond its initialcircumferential position and puttin the beads into pressureexertingcontact with the hoop-edges.

7. A metallic barrel including a body and a rolling-hoop having apreformed inwardly.

opening circumferential recess, the body of the barrel bein displacedoutwardly into the recess the ull width of, but less than full depth of,said recess exerting pressure oppositely on'the inner edges of saidrecess.

8. A metallic barrel comprising a generally cylindrical body and anencompassing sheet-metal rolling hoop, the latter having between itsedges a pre-formed outwardly displaced bead, said body having outwardlydisplaced beads closely flanking both edges of the hoop and having anintermediate portion outwardly displaced into the hoopbead, saidflanking-beads of the body bearing with pressure against the edges ofthe hoop.'

9. A metallic barrel comprising a body and an encompassing rolling-hoop,the latter preformed to present two flange zones and .an interveningoutwardly presented bead,

expande into the hoop bead, and registering parts of said body'and thehoop-flanges being jointly displaced outwardly beyond their preformedpositions and in close contact with each other.

11. A metallic barrel comprising a body and a rolling hoop, said bodyhaving outwardly displaced beads closely flanking the edges of the hoop,and said head and hoo having super-imposed zones between said beadsequally outwardly bulged and stretched.

12. A metallic barrel comprising a sheetmetal body and a sheet-metalrolling hoop, said body having outwardly-displaced beads closelyflanking and contacting with the edges of the hoop, and said body andbead having zones of their super-imposed portions, between said beads,similarly bulged and stretched outwardly, the flanking beads maintainingpressure-contact with the hoop edges. 7

13. A metallic barrel having a rollinghoop pre-formed to present aprojecting bead with an inwardly facing channel flanked by integralflanges, the body of said barrel having outwardly directed beads snuglygripping the flange-edges and pressing thereon.

14. A metallic barrel having a rollinghoop pre-formed to present aprojecting head with an inwardly facing channel flanked by integralflanges, the body of said barrel having outwardly directed beads snuglygripping the flange-edges and pressing thereon, the flanges of said hoopand the underlying body-zones of the barrel being correspondingly bulgedoutwardly.
